How to unlock Xiaomi Mi9: from bootloader to Mi-Account

The Xiaomi Mi9, released in 2019, is still popular with users thanks to its powerful hardware and custom firmware support. However, owners often face the need to unlock — whether it’s a bootloader to install alternative software, Mi-Account after buying a used device or blocking FRP after a reset. In this article, we will analyze all the current ways to unlock the Mi9 in 2026, including official methods from Xiaomi and workarounds for experienced users.

It is important to understand that procedures vary depending on the type of lock. For example, unlocking the bootloader requires confirmation through the Xiaomi account and waiting 7-30 days, whereas unbinding the Mi Account may require contacting for support or using specialized tools.

If you have purchased the Mi9 handheld and cannot activate it because of a previous owner's account, don't panic. In most cases, the problem can be solved without going to the service center, the main thing is to follow the instructions clearly and not miss the steps of the check.

1. Unlock bootloader on Xiaomi Mi9

The Xiaomi Mi9 bootloader is blocked by the manufacturer by default, which prevents custom firmware installation (such as LineageOS or Pixel Experience), root rights or modification of system files. The official way to unlock involves using the Mi Unlock Tool utility and confirmation through the Mi Account.

The process consists of several stages:

• 📱 Linking Xiaomi account to the device (required!)
• 🔗 Request permission to unlock through Mi Unlock Tool
• ⏳ Waiting for confirmation (from 7 to 30 days)
• 🔓 Direct Unlocking via Fastboot

Since 2021, Xiaomi has tightened the policy: now to unlock requires confirmation through the SMS This made it more difficult for users who bought a device without the original device. SIM-Here's a step-by-step guide to meet current requirements.

Create/log in to Mi-Account|Link the account to the device in the settings|Enable debugging on USB and OEM-unlock|Download Mi Unlock Tool from the official website|Prepare the cable. USB (preferably original)

Important: Once the bootloader is unlocked, all data will be deleted from the device (full reset), save important files to your computer or cloud in advance, and note that unlocking will void the Xiaomi warranty (if it is still valid) and may cause problems with air updates (OTA).

2. Unbinding the Mi Account (bypassing the Xiaomi account)

One of the most common problems with hand-held Mi9 purchases is linking to the previous owner's account, and even after a Recovery reset, the device may require a username and password from the Mi Account, and you can only officially unlink if:

• 🔑 You have the data to log into the account of the previous owner
• 📧 You can contact the seller and ask them to remove the device from the list at i.mi.com.
• 🛠️ You have a check/guarantee card (to apply for Xiaomi support)

If neither of these options works, there are still informal methods, and the most reliable ones are:

1. Use of the EDL-mode (emergency firmware via MiFlash with an authorized account).
2. Fastboot bypass (for older versions of MIUI).
3. Specialized services (e.g. DC-Unlocker or Mi Account Remove Tool)

It is worth noting that with the exit MIUI 12 and newer Xiaomi has closed most of the vulnerabilities that allowed you to bypass the account through ADB Or Fastboot. Now, it's more often than not authorized. EDL-Account (access cost - from the $5 $20 depending on the seller).

⚠️ Note: Mi Account bypassing methods through third-party tools may result in blocking IMEI or turning the device into a brick. Before using, check the reviews of the tool in profile forums (for example, 4PDA or XDA-Developers).

FRP (Factory Reset Protection) Release

FRP (Factory Reset Protection) is Android protection that is activated after resetting if a Google account was attached to the device. On Xiaomi Mi9, FRP can block access even after successfully bypassing the Mi Account.

The easiest way is to enter data from a Google account that was linked to the device, and if you don't know it, try to restore access through accounts.google.com. If that's not possible, the technical methods remain:

1. Connect the Mi9 to your PC and start the ADB.
2. Follow the command: adb shell am start -n com.google.android.gsf.login/ (to bypass the lock screen).
3. If ADB doesn’t work, try flashing your device through Fastboot with FRP: fastboot erase frp removed.

On devices with MIUI 13+, these methods may not work due to enhanced protection, in which case only firmware through EDL (with the risk of losing the serial number of the communication module) will help.

4. Unlocking the network (IMEI and SIM-lock)

If you're Xiaomi. Mi9 see SIM-card or make a mistake «SIM-The network is blocked, the problem may be related to:

• 📶 Blocking. IMEI (For example, after a failed firmware).
• 🔒 Operator lock (the device is tied to a specific operator).
• 🛠️ Damage to the communication module (hardware failure).

For diagnosis, check the status IMEI, If you type in the phone app code *#06#. If you see zeros or "unknown" instead of the number, it indicates a software failure. IMEI through:

• 📝 Enter the original number via Engineering Mode (code #4636##).
• 🔧 Modem Module Firmware via Fastboot.
• 🔨 Using tools like SN Writer Tool (requires authorization).

If the device is locked by the operator (for example, it was purchased under a contract), you can request the unlock officially from the provider.

1. IMEI number (to find out via *#06#)
2. Documents confirming the purchase (check, contract).
3. Contact the operator support service (sometimes unlocking is possible for a fee).

⚠️ Attention: Attempts to change IMEI Xiaomi Mi9 using informal tools (e.g. Maui) META Chimera Tool can lead to locking the device at the server level of Xiaomi, in which case it will be impossible to restore communication without contacting the service center.

5 Unlocking after "brick" (brick)

Brick: A condition where the Mi9 doesn’t turn on, doesn’t respond to buttons, or hangs on the MI logo.

• 🔄 Failed firmware update.
• 🔧 Error when unlocking the loader.
• 🛠️ Damage to system files after root rights.

Depending on the type of “brick” (soft or hard), the methods of recovery are different:

To recover via Fastboot:

1. Download the official firmware for Mi9 (codename cepheus) from en.miui.com.
2. Unpack the archive and start the command: fastboot flash all file firmware.img
3. Wait until the process is completed (it can take 10-15 minutes).

If the device is not defined in Fastboot, try to transfer it to the Fastboot. EDL-regime:

1. Turn off the phone.
2. Press Volume up + Volume down and connect to the PC.
3. Install the Qualcomm HS-USB QDLoader 9008 driver.
4. Sweep your device through MiFlash with an authorized account.

6. Alternative Unlocking Methods (for Power Users)

If standard methods don't work, you can try alternative solutions, which require technical skills and carry risks, but sometimes they are the only way out.

1. Use exploits to bypass Mi Account

Some versions of MIUI (e.g. MIUI 10–11) run vulnerabilities that allow you to reset your account via ADB.

adb shell content insert --uri content://settings/secure --bind name:s:user_setup_complete --bind value:s:1

This method puts the device into a "first start" state, bypassing the lock screen, but it doesn't work on newer versions of MIUI.

2. firmware through TestPoint

If the Mi9 is not included in the EDL, you can use TestPoint, a special point on the board, the circuit of which puts the device in emergency mode.

1. Take your phone apart and find TestPoint (location depends on the board revision).
2. Close the contacts with tweezers or wire.
3. Connect. USB-plug-in.
4. Flush the device through MiFlash.

3. Use of third-party boxes (e.g. UMT or Z3X)

Professional tools like UMT Pro or Z3X Box allow you to unlock your Mi Account, reset FRP, and restore your IMEI without authorization, but the cost of accessing these tools starts at $50 and requires experience.

⚠️ Buying “cheap” accounts for MiFlash or EDL On dubious sites, it is fraught with fraud. Often sellers offer "perpetual" accounts that are blocked after a few days.
